They have linked to an example from one of the blog posts: https://www.reddit.com/r/programming/comments/14vnipl/rust_f...

The problem is FUD. Some guy at a company gets told he has to wait for legal to approve some open source project or initiative that happens to use JS in the name, because his boss heard there’s a trademark issue, and the enthusiasm fades and the idea gets sidelined. There’s probably been thousands of tiny little instances of FUD like that, which we’d never hear about, and which have led to good things not happening.

One clear instance of FUD we do know about is the spec itself is not titled with the name of the language it specifies, which is then its own source of confusion for newcomers trying to learn the web platform, and makes it harder for old timers to explain things, and is generally annoying. Complexity. Confusion. Doubt. Inaction.

Removing legal FUD from the world is a good cause. I don’t mind if it also works as a good marketing play for Deno.

I think it's mostly a marketing play by Deno.
